Feel like a good sponge costume would allow you to pee right where you are.
Echinoderms:
I guess it depends on what kind of sponge, but I think in all likelihood since most sponges have no symmetry that this comes down to the same politics as an agender person choosing a bathroom.
Flounders are not bilaterally symmetrical.
Dafuq you say about me?
YOU’RE NOT BILATERALLY SYMMETRICAL
In the tree of life, flounders are a sub-sub-…-sub-species of bilaterally symmetrical animals: https://www.onezoom.org/life/@Holozoa=5246131?otthome=%40_ozid%3D1&highlight=path%3A%40Apionichthys_finis%3D3640785&highlight=path%3A%40Bilateria%3D117569#x2913,y-2310,w8.2796
Edit: let me preemptively be a pedant to myself and say that “sub-…-species” is wrong because “bilaterally symmetrical animals” is not a species. Flounder is itself a species AFAIK, not a sub-species of anything. It is a descendant of the common ancestor of all bilaterally symmetrical animals. There, now surely no one will find anything to be pedantic about :D
Just like starfish!
Forego the illusion of species and families. It’s taxa all the way down.
They’re “differently symmetrical.”
It depends on whether it was a larvae or not.
Pretty sure from my B- in zoo that sponges eat from what amounts to our waste hole.
So you are supposed to piss in the punchbowl and drink from the toilette.
Toilette du fromage.
They are a single orifice kind of animal. Take a gulp of sea water, sift oit the goodies, and expel the rest
Yeah. ok. See what kind of biological insight a B- gets you?
What if you take off the costume? Humans aren’t entirely bilaterally symmetrical (at least not on the inside) and obviously not radially symmetrical so the paradox continues.
Is any animal perfectly bilaterally symmetrical?
